Chapter General
Shunt controlled additional heat General This function enables an external additional heater, e.g. an oil boiler, gas boiler or district heating exchanger to aid with heating. The indoor module controls a shunt valve and a circulation pump (GP0) via the accessory card in. If the heat pump does not manage to keep the correct supply temperature (BT), the addition starts. When the boiler temperature of (BT) has been increased to about C, the indoor module transmits a signal to the shunt (QN) to open from the addition. The shunt (QN) adjusts so the true supply temperature corresponds with the indoor module's theoretical calculated set point value. When the heating demand drops sufficiently so the additional heat is no longer required the shunt (QN) closes completely. Factory set minimum run time holding the boiler prepared is hours (can be set in menu..). Pipe connections The external circulation pump (GP0) is positioned according to the outline diagram. Shunt valve The shunt valve (QN) is located on the flow line to the climate system after the heat pump according to the outline diagram. Connect the flow line from the heat pump to the external heat source A AB via the T-pipe to port B on the shunt valve (closes at reduced signal). Connect the flow line to the climate B system from the shunt valve to the common port AB (always open) Connect the flow line from the external additional heat to the shunt valve to port A (opens at increased signal). Temperature sensor Install the boiler sensor (BT) in a suitable location in the external addition. External supply temperature sensor (BT, connected in ) must be installed on the supply line to the radiators, after the shunt valve (QN). K Install the temperature sensors with cable ties with the heat conducting paste and aluminium tape. Then insulate with supplied insulation tape. NOTE Sensor and communication cables must not be placed near power cables. Chapter Shunt controlled additional heat

Active cooling (-pipe) General Connecting this accessory makes it possible to control production of cooling. The cooling system supplies cooling from the heat pump using a circulation pump (GP) via a reversing valve (QN). For the installation to work the cooling system must flow freely permanently, for example using a volume vessel for cooling. Operating mode cooling is activated by the temperature of the outdoor sensor (BT) and any room temperature sensors (BT0), room units or separate room sensors for cooling (BT) (if two different rooms are to be heated respectively cooled at the same time for example.) When cooling is required, the cooling reversing valve (QN) and the circulation pump (GP) are activated. Cooling production is regulated according to the cooling sensor (BT) and a cooling set point value that is determined by the selected cooling curve. Cooling degree minutes are calculated in response to the value on the external temperature sensor (BT) for cooling out and the cooling set point value. As an accessory, cooling reversing valve is required, e.g. VCC/VCC. Pipe connections General Pipes and other cold surfaces must be insulated with diffusion-proof material to prevent condensation. Where the cooling demand is high, fan convectors with drip trays and drain connection are needed. Reversing valve, cooling/heating The reversing valve (QN) is located in the system on the supply line from the heat pump ahead of another reversing valve according to the outline diagram. B AB A Temperature sensor Temperature sensor (BT) is mounted on the supply line to the cooling system at the T-pipe connection to the volume vessel (CP). K Install the temperature sensors with cable ties with the heat conducting paste and aluminium tape. Then insulate with supplied insulation tape.
